The National Weather Service has issued a flood warning for Mendenhall Lake and Mendenhall River in Juneau, following the suspected release of water from a glacially dammed lake.
Last month, a glacial outburst helped push floodwaters over side roads and into some garages and resulted in Mendenhall Lake rising to 11.82 feet, a new record.
Meteorologist Edward Liske says lake levels are expected to reach 11.6 feet by late Tuesday or Wednesday morning. Moderate flood stage is 10 feet.
The agency said water has been reported in some garages along View Drive.
Liske said officials were re-evaluating the river gauges.
He said people at the Mendenhall Glacier visitor center reported seeing ripples on the side of the glacier, indicating another outburst had occurred. The city also received recent soaking rains.
